Title:
ENVIRONMENTALLY-FRIENDLY COMPOSITE BYPASS SEEPAGE-PREVENTION FLEXIBLE VERTICAL ISOLATION SYSTEM, AND INSTALLATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/047643
Kind Code:
A1
Abstract:
Disclosed are an environmentally-friendly composite bypass seepage-prevention flexible vertical isolation system, and an installation method. Said isolation system comprises bypass seepage-prevention members (1) for retarding pollutants in underground water and soil; each bypass seepage-prevention member (1) comprises a prefabricated fiber-reinforced cement-based material or a carbonized magnesium oxide-based material, closed bolts (3) having two reserved openings are formed on the surface of the bypass seepage-prevention member (1), one flexible seepage-prevention wall body (2) is sandwiched between the two bypass seepage-prevention members (1), and the flexible seepage-prevention wall body (2) is composed of a rectangular high-density polyethylene geomembrane. The system can solve the leakage problem caused by poor contact between a geomembrane and a water-impermeable layer at the bottom of a tank, and can meet the requirement of maintaining the seepage-prevention property in extreme earthquake or large geological activity; the system uses an environmentally-friendly material, magnesium oxide, accelerates the formation of members by using a carbonization method, and can comprehensively use an environmentally-friendly material, absorb carbon dioxide, and efficiently produce highly-ductile bypass seepage-prevention materials.
